HORSE-OVERSHOE.

Specification of Letters Patent.

Patented July 29, 1913.

Application filed January 3, 1912. Serial No. 669,146.

To all whom it may concern Be it known that I, RICHARD WHITAKER, a citizen of the United States, residing at New Brunswick, in the county of Middlesex and State of New Jersey, have invented new and useful Improvements in Horse0vershoes, of which the following is a specification.

This invention relates to horse overshoes; and it comprises a readily attachable and removable calk-bearing plate or element intended for use in connection with a horseshoe, said element comprising spaced calks projecting downwardly from its face, for ward clamping means intended to engage the sides of a horseshoe toward the front and rear clamping means comprising a cross-bar adapted for engagement with the heel calks of the horseshoe, a clamping nut removably mounted in said plate and a bolt connecting said cross-bar and said nut; all as more fully hereinafter described and as claimed.

It is the object of the present invention to provide a strong, permanent and solid calked boot or pad-plate readily and quickly attachable to and removable from the ordinary horseshoe, having the elements sus ceptible to great wear, of simple and easily renewable construction and being cheap but strong, a prime object being the provision of an overshoe which is cheap'to make and effective and durable in use. To this end, I provide a face plate, or like element, carrying calks on one face and of about the dimensions of the ordinary horseshoe. While this plate for special purposes may be of aluminum, bronze or other metal, it is for most purposes best made of steel; andIshall so describe it hereinafter. Advantageously it may be a simple nearly square stamped plate of steel having the sides somewhat dished so as to provide four corner lugs. On these corners may be riveted or welded threaded lugs or bushings for carrying calks. Preferably this is accomplished by stamping through the plate a hole with a serrated edge for each lug or bushing and riveting the same therein, this representing exceptionally cheap and strong construction. Two of these lugs preferably carry lugs or projections bent upward to embrace the front or toe of the horseshoe to resist the backward pull of the shoe when clamped into place. Longitudinally of the plate may be stamped a shallow groove adapted to receive a clamping bolt and transversely crossing this groove may be a nut-receiving slot in which a removable nut will seat. This nut may be threaded on a bolt lying in the groove and rearwardly passing through a cross-bar engaging the heel calks of the horseshoe.

It will be observed that the construction is thus such that the device may be made and assembled cheaply, simply and readily, that each part may be readily replaced, and that the overshoe is strong and effective.

In the accompanying illustration I have shown, more or less diagrammatically, an embodiment of this invention.

In this showing Figure 1 is a plan view of a horseshoe seen from above and carrying the overshoe; Fig, 2 is a plan view of the same from below; Fig. 3 is a view, partly in vertical section of the structure of Fig. 1 along line 33'; Fig. 4t is a view of the plate or pad shown disassembled from the other elements of the overshoe; Fig. 5 is a view of one lug of the plate; Figs. 6 and 7 are views on an enlarged scale illustrating a method of attaching the bushings and calks; and Fig. 8 is a section on line S-8 of Fig. 3 showing the removable nut in position.

In the showing of Fig. 1, element 1 is a horseshoe of ordinary construction; 2 is the plate forming the body of my new calk plate; 8 is a removable cross-bar having it flange 3; 4 is a toe calk on the horseshoe and 4'4t are heel calks. The crossbar bears at an intermediate point a seat for a clamp bolt 5 carrying removable nut 6 having a flanged extension 6 (see Fig. 8). In the upper surface of the plate is a groove 7, with which the bolt registers, carrying a cross slot 7 adapted to receive the nut. At the corners of the plate are mounted calks 8, threaded at 8 to engage internally threaded bosses or bushings 9. These bosses or lugs 9 have extensions 9 adapted to fit orifices in the plate corners having serrated edges 9 After insertion in these orifices, as shown in Fig. 6, these extensions may be flanged or riveted over the upper side of the plate, as shown in Fig. 7, the metal of the extension flowing into the serration of the orifices and thus insuring anchorage of the calk boss or bushing. E11- gaging the forward part of the shoe behind the toe calks are toe grips 10 which form upward extensions of the front calk bosses 9.

In the structure of Fig. 1, the overshoe is seen in place. Flanges or toe-grips 10 engage the forward part of the horseshoe, while cross-bar 3 engages the rear calks, the overshoe being clamped in position by suitably rotating bolt 5 in nut 6. This nut fits into slot 7 but is prevented from passing through by flanges, extensions or lugs 6 which engage the under side of the plate. The groove is in the upper face of the plate and is of such size and depth as to fit the bolt fairly closely and to support the same laterally.

As will be seen, plate 2 is of a cheap and simple construction, being merely a stamped and slotted piece of sheet steel. Instead of being solid, the plate may take the form of a more or less open framework, suitable provision being made, of course, to receive and support the removable clamping nut. Ordinarily, however, the solid plate is preferable on account of the protection it affords to the horses foot and also because of simplicity of manufacture. It is desir able that the locking bolt be supported laterally along the greater part of its length as shown, this construction giving increased strength and rigidity to the structure and also with the solid plate preventing the accumulation of snow known as balling. The bushings should be fastened in holes in the plate which are not round, serrated holes or holes having some angles into which the metal can run being desirable to prevent turning. The provision of bushings serving the double purpose of calk-holders and toe-grips is desirable because it c-heapens the cost of manufacture. The calks in turn are merely threaded bars which engage the threaded rivet elements 9, the calk points being as sharp as desired. lVith this construction, the calks can be easily renewed whenever bent or worn. Similarly, the bolt and nut are simple and cheap elements susceptible of cheap and ready renewal.

lVhat I claim is 1. In a horse overshoe, a plate provided with a transverse slot in mid-portion, calks mounted on said plate at its corners, clamping lugs secured to said plates and arranged to engage the forward part of a horse-shoe, a flanged and threaded nut adapted to seat in said transverse slot, a bolt arranged longitudinally in said plate and engaging said nut and a flanged cross-bar having a seat for said bolt and adapted to engage the heel calks of said horse-shoe.

2. In a horse overshoe, a plate provided with a transverse slot in mid-portion and a longitudinal bolt-receiving groove, calks mounted on said plate at its corners,.clamping lugs secured to said. plates and arranged to engage the forward part of a horse-shoe, a flanged and threaded nut adapted to seat in said transverse slot, a bolt engaging said nut and a flanged cross-bar having a seat for said bolt and adapted to engage the heel calks of said horse-shoe.

3. In a horse oversho-e, a stamped steel plate having a slot in a mid-portion, a bolt-- receiving groove and orifices in its corners, internally threaded lugs or bosses riveted in said orifices, two of said lugs having extensions adapted to engage the fore part of a horse-shoe, calks threaded into said lugs, a nut removably arranged in said slot and registering with said roove and having wings adapted to engage one face of the plate, a bolt engaging said nut and adapted to rest in said slot and a flanged cross-bar having a seat for said bolt and adapted to engage the heel calks of said horse-shoe.

l. In a horse overshoe av plate having holes with serrated edges, bushings in said holes having portions thereof in contact with said edges and securely held in place there by, calks for said bushings, and means for connecting said plate removably to a horseshoe.

5. In a horse overshoe, a plate to which are affixed bushings serving both as calkholders and toe-grips in combination with a heel-grip and means for drawing said grips together.
